Clicks empty promises

I called into the call centre numerous times I will say because I lost count. I lost my clicks card I used a virtual card but due to phone issues lost that I eventually got another card and called in for them to link the card. I shop my toiletries and my kids toiletries at clicks so I know collectively I should have cash back anyway I called in and told the agent my issue I said to her I got to the teller and was advised I have a R10 which I know is not possible because I buy way to much. She checked and said collectively I have more then R50 she will put it on the card I was told by them to use it would reflect by the 24th well two months later I still don't have cash back every time I call I'm told they linked my profile but nothing profile not linked no cash back no points. The turn around time is not even accurate. What am I to do I purposely shop at clicks because I save my cash backs for a rainy day as a single mother it comes in handy but this time around when I needed it it wasn't available because the people who were suppose to help me didn't.
